Arioka Kofun Cluster

This is a group of tombs located in a scenic area overlooking the town of Zentsuji City. This group of tombs are said to be those of a distinguished family, the ancestors of Saint Kobo Daishi. Zentsuji, historically known as the city of tumulus mounds. Over 400 sites of varying sizes, have been discovered in the greater municipal region. Among these, the one considered to be of an equally distinguished status of a chief, is the Ohakayama tomb in the center of the Arioka group. This keyhole shaped tomb is about 46 meters in length and was built around mid-sixth century. From the stone burial chamber earthenware, ornaments, weapons and horse tack were excavated. April 29th is the official tumulus day, designated by the city. On this day, the normally sealed off, yokoanashiki horizontal stone chamber of the Ohakayama tomb and the Noda-in tomb mound is opened to the public for viewing.
